The Growth and Development Prospects of Worldwide Fiber Optic Sensor Market

FBG sensor marketOptical fiber sensors have seen increased acceptance and widespread use in the scientific world in the last few decades. Against the background of other sensor types, fiber Bragg grating sensors have become widely known and popular. Such FBG sensors are able to measure the various parameters of the substances studied in the research of scientists and engineers. These are such parameters as chemical and biological agents, temperature, strain, pressure, and many others. In addition to this, the optical fiber sensor technology and fiber Bragg grating sensors, in general, have the increased flexibility of design to be used as a single point or multipoint arrays. Also, fiber optic systems and devices based on them have their own relatively low cost that makes them available for use in the different fields and industries. However, it is necessary to actively engage with the problems of increasing the FBG sensors’ attractiveness for business.

Nowadays fiber optic sensors markets are in a relatively early development stage so it is difficult to access and forecast with accuracy. Furthermore, the market segments are fragmented due to the variety of sensing applications and industries where they are applied. The global market of the fiber Bragg grating products is primarily composed of three key segments:

  1. sensing devices (bare FBGs for sensing applications, packed FBG sensors, and FBG arrays)
  2. instrumentation (fiber Bragg grating interrogating instruments and related components: multiplexers, switches, data acquisition systems, software, and graphical user interfaces)
  3. system integration and installation (implementation tools for the fiber optic solutions and fiber optic system installations like design, planning, system integration, customer training, service, etc.)

According to the latest data, the worldwide demand for bare and packaged FBGs is more than 10, 000 pieces per year. And besides that, the worldwide demand for FBG arrays is estimated to be between 100s to 1, 000 arrays per year. The combined present global market size of this segment is between $15M to $35M USD a year with an annual growth rate of 15% to 25%. The total market size of all products in the FBGs product line is estimated to be in excess of $50M USD.

Future applications of FBG sensors will possibly develop over time depending on cost reduction and development of specialized and application-specific packaging. It is expected that more conventional and popular applications such as discrete strain and temperature sensing will continue to evolve and acquire greater market shares. Newer applications in chemical, biological, and medical sensing will lead to the creation of a new generation of fiber optic products that will perform specific agent or parameter sensing functions.

In order for fiber optic products to penetrate into mainstream industrial processes,  appropriate transducers must be developed. FBGs must meet such criteria as ecological strength, appropriate sensitivity, and the correct dynamic range. Also, they need to be early replaceable without a description of the FBGs network and adhere to engineering standards, either existing now. One of the most important conditions for the development of the global market of fiber optic products is seamless integration with existing control system architectures.

Ubiquitous optical fiber strain sensors against a background of large-scale urbanization

FBG strain sensors in urbanization processFiber Bragg gratings are often used in strain sensing especially in such places where the environment is harsh (for instance, high-EMI, high-temperature, or highly-corrosive). Strain measurement is imperative during prototype design and testing. Strain measurements ensure that materials perform as they should and that the equipment is safe and durable. Measuring strain is crucial for testing complex structures, like aircraft, turbines, etc. There various ways in which stress can be measured, but it is widely accepted that FBG sensors are the most efficient way of strain measurement.

There are two types of applications of the fiber Bragg grating strain sensors:

  • Long-term Static Strain Sensing. The main issue in the long-term static strain test is an interest in measuring the long-term static strain of the component in question. In order to carry out the above operation, it is necessary to set up the grating on the structure, find out what the initial wavelength is, and then within a set period of time to detect and record the changes that have occurred. Also, it is possible to return to the structure, reattach, and refer back to the initial wavelength. As a result, it becomes possible to obtain the determination of what this strain is from the initial condition at that time. The ability to disconnect your monitoring instrumentation and return for results after a large amount of time such as months or even years is a very great advantage of fiber Bragg grating sensors. For instance, in the case of bridges, it is common for engineers to visit the bridge and conduct the impact testing using an impact hammer on the different parts of the bridge. This is time-consuming and even hazardous because of the height of some bridge structures. The distribution of a number of FBG sensors throughout the bridge and the attachment of the instrumentation to this bridge on a periodic basis is a much more efficient solution. This is only one of the good examples to demonstrate the effectiveness of the fiber Bragg grating strain sensors. Besides bridges, other examples of using FBG for long-term static strain testing are buildings, piers, and structures in high earthquake-prone areas.
  • Dynamic Strain Sensing. The different structures may have very-low-frequency modes, and they may also have higher modes due to the effects of wind and tide. Most earthquakes and other earth tremors are low-frequency events.  Fiber Bragg gratings can be attached to the structures and monitored for the vibrations during the earth’s tremors and earthquakes. The low-frequency dynamic strain testing can help in determining the reaction of high-rise buildings to the wind. In addition to this, FBG sensors create connections with peers and other shore structures to determine their vibrations during the ebb and flow of tides. Dynamic strain testing can also be performed on transportation vehicles like automobiles, trains, and airplanes. In addition to civil structures and vehicles, there are a number of other applications for dynamic strain testing and vibration stress testing using fiber Bragg gratings. FBG sensors can be attached to industrial machinery to determine the frequency and amplitude of the stress vibrations.

Distributed Temperature Sensing systems: Benefits and Applications

Distributed Temperature SensingOne of the most promising directions in the development of systems for controlling of temperature of high-voltage power lines, fire alarm systems, oil and gas fields, and others are DTS systems. Distributed Temperature Sensing Systems is a rising technology which will be further actively developed in the near future. According to the forecasts, the price of such fiber-optic DTS systems will continue to decline while the productivity of them will continue to increase. Distributed Temperature Sensing technology becomes more applicable and more popular for many applications in a wide range of industries.

DTS systems were actively involved in various areas of scientific and engineering developments since the 1980s as temperature systems which can measure temperature with a high degree of accuracy over significant distances. In addition to this, such optoelectronic systems were able to provide a continuous profile of the temperature distribution along the fiber-optic cable or other devices. The main measuring principles were based on detecting the back-scattering of light using the Rayleigh, Raman, and Brillouin principles.

The key to the understanding of fiber-optic Distributed Temperature Sensing systems is awareness of the fact that the optical fiber itself is the sensor and the instrumentation provides measurements on every 1m along the length of the fiber. What does this mean? This means that the operator is able to receive temperature information at all points from the moment of cable installation. Real advantages of DTS systems become apparent when a temperature profile of the installation is required or when a large number of sensing points is crucial. DTS systems are much more convenient than any conventional temperature sensing technology.

Distributed Temperature Sensing technology becomes practical for many applications. For instance, one of the most promising technologies based on the DTS principle is linear optical fire detection. Such fire detection allows us to detect fire and localize the seat of the fire within a building with 1m resolution. Also, DTS systems are applied, for instance, in the oil and gas industry. The systems in question are used to monitor the temperature log of the well. In addition to this, fiber-optic DTS systems provide an opportunity to upscale the measurements to large spatial extents and monitor the temporal dynamics of the hydrological processes. Recent enhancements of this technology based on distributed sensing systems have allowed the balance of energy and fluid mass at a watershed scale. However, it is difficult to say that about all cases of DTS application. These systems are involved in the power systems, in cables for better ampacity judgment and in safety applications like the mines are reviewed. So it is not surprising that the number of companies providing DTS systems is growing ever so much.

Optromix is a fast-growing seller of such products from the fiber Bragg grating (FBG) line of products: fiber Bragg grating sensors, FBG interrogators and multiplexers, and, of course, Distributed Temperature Sensing Systems (DTS). Our major goal is to deliver the best quality of fiber-optic sensors to our clients.

Fiber-optic sensors in biomedical applications

FBG sensors in biomedical applicationsThe scientific experience of the last few decades was marked by major achievements in the field of fiber-optic sensors. Optical fiber sensors have certain advantages like immunity to electromagnetic interference and high sensitivity, small size and small weight, large bandwidth, and ease of use and distribution. Over the years, fiber-optic sensors have fastly grown in quality and functionality and have found widespread use in many areas such as defense, automotive, manufacturing, and among various other industries. A wide range of applications was defined for fiber sensors in general and in particular for medical and biomedical applications. Also, these technologies have become more commercially available.

The medical and biomedical industry provides many challenging requirements, for which optical fiber sensors can provide original and reliable solutions. In the coming years, scientists and engineers in the medical and biomedical areas will use fiber-optic sensor turnkey systems for sensing and measuring of any type of physical quantity. Such fiber-optic turnkey systems are a combination of four basic components: a light source, an optical fiber, a sensor element, and a light detector. In such systems, the fiber-optical sensor acts as a light modulator to change a property of light (phase, polarization, etc.).

Possible future applications of fiber-optic sensors in biomedical research include simultaneous collection and analysis of samples for drug safety evaluation for instance. Also, optical fiber sensors help in the identification of drug molecules and in the sensing of biomolecules, effluent monitoring, and overall pharmaceutical quality control of the product. In that context, it’s important to note that light-carrying fibers are potentially useful as physical sensors of temperature, pressure, and rapidation and as chemical sensors of pH, the partial pressure of blood, and glucose.
